Namesake

Namesake is a noun that describes a person or thing that bears the same name as another. In common usage, it most often refers to the person after whom something is named, or to the thing that is named after that person. For example, the Albert Einstein Award is named after Albert Einstein; Einstein is the namesake of the award. The term can also describe a person who shares the same name as another: if two individuals are named John Smith, they are each other’s namesakes.

Origin and etymology: Namesake combines name with sake, with the sense of bearing or bearing the name for the sake of the name. The precise origin is uncertain, but the contemporary meaning centers on sharing or bearing a name. The word has been in use in English since the early modern period.

Usage and distinction: Namesake is versatile but can be ambiguous, particularly when discussing who was named after whom. In more formal or technical contexts, the term eponym is often preferred for the person after whom something is named, while namesake remains common in everyday language for either the person or the thing bearing the name. When two entities share the same name, they can be described as namesakes of one another.
